WELCOME BACK. MOMENTS AFTER THE BOMBING, THE EFFORTS BEGAN TO FIND WHOEVER RESPONSIBLE. THAT NIGHT, A MAN NAMED DAN HE BECAME CRITICAL IN FINDING THEM. HE WAS CARJACKED AND HELD FOR MORE THAN AN HOUR BEFORE HIS DARING MISTAKE. WITH AN AGREEMENT TO PROTECT HIS IDENTITY, HE IS SHARING MORE OF THIS INCREDIBLE STORY. WHEN I LOOK BACK , I STILL CANNOT BELIEVE THAT IT HAPPENED TO ME. I FEEL LIKE IT WAS SOMETHING THAT HAPPENED IN A MOVIE. IT WAS REAL-LIFE TERROR FOR DANNY. THE 27-YEAR-OLD CONSIDERS HIMSELF LUCKY AND SO MANY WAYS. LUCKY BECAUSE HE WAS CHEERING ON THE RUNNERS AT THE FINISH LINE ONE YEAR AGO BUT LEFT TWO HOURS BEFORE THE BOMBS EXPLODED. I WAS LUCKY BECAUSE I DID NOT GET HURT. I CANNOT IMAGINE THOSE GUYS COMING BACK TO ME. HE CAME AS A STUDENT FROM CHINA. HE WAS HEARTBROKEN FOR HIS ADOPTED CITY. HE SAW THE PHOTOS OF THE SUSPECTS NEVER IMAGINING WHEN HE PULLED OVER TO SEND A TEXT MESSAGE ON THE NIGHT OF APRIL HE TEENS, 2013, THE ROTORS WOULD TARGET HIM. TAMERLAN REACHED IN THE PASSENGER WINDOW OPENING THE DOOR AND POINTED A GUN AT DANNY. HE ASKED ME , DO YOU KNOW THE BOSTON MARATHON BOMBING? HE SAID, I DID THAT. I JUST KILLED AN OFFICER IN CAMBRIDGE. AFTER DRIVING TO A MORE SECLUDED LOCATION, THEY LOOTED ITEMS INTO HIS MERCEDES SUV AND ORDERED HIM INTO THE PASSENGER SEAT. TAMERLAN WAS NOW BEHIND THE WHEEL. I ASKED IF HE WAS GOING TO KILL ME. HE SAID HE WAS NOT GOING TO KILL ME. YOU DID NOT BELIEVE HIM? I DID NOT. I SAID I'M FROM CHINA. THE CHINESE ARE PRETTY FRIENDLY TO MUSLIMS. THEY USED HIS CAR TO TAKE MONEY FROM AN ATM AND TALK ABOUT HEADING TO NEW YORK BUT HIS SUV WAS LOW ON GAS. WHEN THEY PULLED INTO THE SHELL STATION, THE YOUNGER BROTHER WENT INSIDE TO PAY IN THE DOORS WERE LEFT UNLOCKED. HE MOMENTARILY PLACED THE GUN AND THE DRIVER DOOR COMPARTMENT. I COUNTED DOWN, ONE, 2, 3, FOUR, AND JUMPED OUT. AND YOU RAN. LIKES I RAN VERY FAST, PROBABLY FASTER THAN ANY OTHER TIME IN MY LIFE. DID YOU LOOK BACK? I DID NOT LOOK BACK. HE SLIPPED RIGHT THROUGH HIS FINGERS. YOU COULD FEEL HIM REACH FOR YOU? I COULD FEEL THE WIND OF HIM TRYING TO GRAB ME. HE MADE IT INTO THE MOBILE STATION AND YELLED TO THE STARTLED CLERK. I BEGGED HIM, CALL 911 RIGHT AWAY. I WAS SO AFRAID THAT THOSE GUYS WERE GOING TO BE COMING BEHIND ME. THEY SPED OFF IN THE SAME SUV THAT WAS INVOLVED IN THE SAME WATERTOWN SHOOTOUT, THE SAME SUV THAT RAN OVER HIM IN THE STREET. AFTER AN HOUR AND A HALF, HE WAS FREE. DAMIAN FRIENDS HELPED HIM COPE WITH THE ORDEAL AND HE TOOK OFF -- DANNY'S FAMILY AND FRIENDS HELPED HIM COPE. HE TOOK UP RUNNING. HE WILL CHEER ON THE RUNNERS AT THE FINISH LINE AGAIN THIS YEAR. HE WILL FEEL LIKE ONE OF THE LUCKY ONES. YOU DID NOT GIVE UP. MOST IMPORTANT IS THAT THE PEOPLE HERE. HE NOW CONSIDERS BOSTON HOME.

Hillary Clinton did not have a State Department email account while she served as America's top diplomat, a senior state department official said Monday, and instead used a personal email account during her four years on the job.
